Alright, so I got ML Soundwave last week and I just now got a miniSD card for it today. I put some music on it...and it won't play. At all. The light blinks 3 or 4 times, then stops and no music plays. I can't figure out why. I did everything it says in the instructions (and by that I mean I looked at the picture showing how to insert the card. Dammit, I wish I could read Japanese). Can anyone help me out?
